AWMI(L mm This invention relates to a flash-light, and both longitudinally and radially so the tension the principal object is toprovide such a device thereof will ilrmly hold the lamp and battery in' which, in addition tobeing air, dust and watercontact and also so the radial tension will hold proof, is also practically unbreakable andshockthe open rubber end oi' the body in contact with prooi'. the rim of the lens to form an air-tight closure 5 To that end I provide a flash-light having a thereto. y resilient body preferably formed of rubber in Fig. 7 is a view analogous to Fig. 6 with the which the battery, lamp and lens are enclosed so interior parts removed and showing the rubber the interior is air, dust and water-prooi for the body contracted both longitudinally and radially.

I

'gli of' the rubber body, .v Preferably I provide a rubber cap 29 that is 111g, 5 is mother cross section on the line 5.- extended over the'head I I5 to close the open end oi' Fig 3 showing the rim of the lamp trame in Il and to additionally protect the lens Il when 50 co withthegegmentgl terminal thgtispartthe flash-light is not in use. This cap is of 1y imbedded in the inner wall oi' the body at its great use in protecting iShe -lens lll when e plano-convex lens is used, such as is shown in 3 ig o, do' view of the rubber body with Fig. 3. Also the cap aids in preventing the parte mined therein, showing it expanded passage of air, dust or moisture into the cham- 55 Cil ber I2 to thereby have a deteriorating eiIect on the battery. In other words, I greatly prolong the life of the battery by having it enclosedV in a relatively airtight chamber.

Preferably the switch casing 3i is arranged outside of the cylindrical body with its flanged edges 30 embedded in the rubber wall so that air, dust or Water 'cannot enter the chamber I2 through the switch.

The end 21 and also the flange 28 are arranged to protect the interior parts from damage in the event that the dash-light is roughly handled.

As is well known, ash-lights are extensively used in garages, shops and the like having cement oors on which the flash-lights often accidentally fall to their serious injury; and also as is well known, the heavy battery end of the flash-light Vin long falls hits iirst, and for that reason I greatly reinforce the rubber end 21 so it will enable the flash-light to rebound when it falls to thereby take the shock oi of the interior parts so they will not be injured.

Also the iiange 28 is extended to protect the lens I1 as described.

My hash-light is used in the usual way. Either the slide 22 or push button 23 is used to move the spring terminal 2l into contact with the' terminal 20 when the lamp is to be lighted. t is obvious that when the slide 22 is used to form this contact the lamp will remain lighted until the slide is reversely moved; but when the push button 23 is actuated to .make this contact the spring tension of the terminal 2l will automatically release it from the terminal 2li as soon as pressure is released on the push button. i

As semidiagrammatically illustrated in Figs. 6 and '7 the rubber body l0 and head H0 are constructed so the 'body is expanded longitudinally and the head radially when theinterior parts are secured therein, so that both the longitudinal and radial tension aid in forming an dust and water-tight seal between the open end ll and the lens I1.

What claim as my invention is:

1. A- ash-light including a hollow cylindrical rubber body having an open and a closed encl,A a segmental terminal partly imbedded in said body adjacent its open end, a battery in said body, a lamp frame having an annular rim Vin contact with said terminal, a lamp in said frame, a metal casing on the exterior oi said body that has its edge portion embedded therein, a metal strip connecting said segmental terminal with a terminal within said easing, another metal strip connecting said casing with an end accises oi' said battery to complete an electrical circuit through said lamp, and a push button slide in said casing for opening and closing the circuit through said lamp, said flash-light constructed so that the longitudinal and radial tension of said body holds the interior parts together.

2. A flash-light including a hollow cylindrical rubber body having an open and a closed end, an inwardly extending annular rubber ilange at the open end of said body, a segmental terminal partly imbedded in the inner wall of said bOdy adjacent its open end, a battery in said body, a lamp frame having an annular rim in contact with said terminal, a lamp in said frame that is in circuit with said battery, a casing having edge portions embedded in the outer wall of said body, a metal strip embedded in the Wall of said body that connects said segmental terminal with another terminal within said casing, another metal strip embedded in the wall 0i said body that connects said casing with one end of said battery to thereby complete an electrical circuit through said lamp, and a push button slide in said casing for engaging or disengaging the terminal therein to thereby open or close the electrical circuit through said lamp, said hash-light constructed so that longitudinal and radial tension of said body holds the interior parts together.

3. A flash-light including a hollow cylindrical rubber body having open and closed ends, an inwardly extending annular rubber iiange at the open end of said body, a segmental terminal partly imbedded in the inner wall of said body adjacent its open end, a battery in said body, a lamp frame having an annular rim in contact with said terminal, a lamp in said frame that is in circuit with said battery, a casing having edge portions embedded in the outer wall of said body, a metal strip embedded in the wall of said body that connects said segmental terminal with another terminal within said casing, another metal strip embedded in the wall oi' said body that connects said casing with one end of said battery to thereby complete an electrical circuit through said lamp, a push button slide in said casing for. engaging or disengaging the terminal therein to thereby open or close the electrical circuit through said lamp, and a lens interposed between said flange and the annular rim oi said frame, said body expanded both longitudinally and radiallyso the tension thereof will hold said parts together and also form an airtight seal between said lens and iiange.
